well, i'm sure many of you have heard about this tragedy. Punkbuster stopped support for cod4.
Most of us have had cod4 installed for a long time and won't directly notice it, but for fresh installs it's problematic. They can't get the right punkbuster files to play on our or many of the other punkbuster protected servers out there. So to accomodate all those fresh (or reinstalling) cod4 players, here is a solution:
1] install punkbuster as usual
2] update punkbuster as usual
3] download these punkbuster files for cod4: http://www.mediafire.com/download/l34pj ... me1/pb.rar
4] copy the "pb" folder from the archive into your cod4 folder, overwriting the old one (if there).
5] you should be able to enjoy the game now.
typically your cod4 folder will be located at one of these paths:
C:\Program Files (x86)\Activision\Call of Duty 4 - Modern Warfare (default for 64bit windows)
C:\Program Files (x86)\Steam\steamapps\common\Call of Duty 4 - Modern Warfare (default for 64bit Steam)
C:\Program Files\Activision\Call of Duty 4 - Modern Warfare (default for 32bit windows)
C:\Program Files\Steam\steamapps\common\Call of Duty 4 - Modern Warfare (default for 32bit Steam)
to make thing extra clear, here is a screenshot of my cod4 folder:
